🔋 90-day warranty is the industry standard for replacement batteries. Batteries naturally lose capacity over time — this normal wear is not covered. Warranty applies to manufacturing defects only.

Restore the battery life of your OnePlus Ace with this BLP921 4500mAh 2S Li-Polymer battery. Released in 2022, the OnePlus Ace features a 6.7-inch AMOLED display and supports 150W SuperVOOC fast charging — reaching 100% in approximately 17 minutes. This battery uses a dual-cell series design (2S) to deliver the factory-rated total capacity for all-day use. Built with grade A cells and multi-layer safety protection against overcharge, over-discharge, and short circuits. CE, RoHS, and UN38.3 certified.
Compatibility Note: Fits OnePlus Ace, OnePlus Ace 5G, OnePlus Ace 150W, and PGKM10. Please confirm your battery model before ordering — BLP921 printed on your existing battery. For reference, Chinese retailers sell this battery for approximately 138 RMB ($19), and US retailers for $23-30. Professional installation is recommended as the phone has a sealed design.
Charging Instructions: Use only a charger designed for 2S Li-Po batteries with SuperVOOC compatibility. The OnePlus Ace supports 150W fast charging with the original charger. Recommended charge current: 2.25A (1C). Never leave the battery unattended while charging. Do not discharge below 6.0V (3.0V per cell).
Battery Care Tips: Avoid full discharge — keep battery level above 20%. Do not expose to high temperatures or direct sunlight. New batteries require 3-5 full charge cycles to reach optimal capacity. For best lifespan, use a certified 150W charger. If you notice swelling or overheating, stop use immediately.

Frequently Asked Questions

The BLP921 battery is compatible with OnePlus Ace, OnePlus Ace 5G, OnePlus Ace 150W, and PGKM10. The OnePlus Ace was released in 2022 featuring a 6.7-inch AMOLED display and supports 150W SuperVOOC fast charging. If your OnePlus Ace battery drains quickly or won't hold a charge, this is the correct replacement. For reference, Chinese retailers sell this battery for approximately 138 RMB ($19), and US retailers for $23-30. Please verify your device model before purchasing.

The BLP921 battery has a capacity of 4500mAh and a rated voltage of 7.74V. This is because the battery uses a dual-cell series design (2S) — two cells connected in series inside a single battery pack. Full charge voltage is 8.9V (4.45V per cell). The battery supports the original 150W SuperVOOC fast charging capability of the OnePlus Ace — reaching 100% in approximately 17 minutes. For reference, third-party retailers list equivalent batteries for $17-30 depending on the seller.

Professional installation is strongly recommended. The OnePlus Ace has a sealed design with strong adhesive. Replacing the battery requires heating to soften adhesive and careful prying to avoid damaging the AMOLED display. If you choose to DIY, watch a full teardown tutorial before starting, use a heat gun at low temperature (no more than 70°C), and never reuse a battery after removal. Incorrect installation may damage the phone or break water resistance. Third-party repair shops typically charge $15-30 for labor.
